CPU Core clock Vs Core Counts

[Ya_Mi]

Okay so someone asked me this question.

If a cpu marketed as 4 core clocked at 4Ghz does that mean each core has 1Ghz core clock speed? or that mean each core has 4Ghz clock speed..but would that make it 16Ghz? if so why its marketed as 4Ghz?

Each core is 4ghz

Btw the boost clock is only on 1 core or 2 recently with Intel

 

But GHz is not all that counts

Ok so each core has 4Ghz of clock speed which is awesome...but why its marketed as 4Ghz? i mean 16Ghz jesus christ that sounds better right for marketing purposes?

Each core run at 4GHz. You cannot stack frequency like that

You should totally work in motherboard manufacturers because that's the same logic used in raising VRM phase count

can't you just explain it right here?

Frequency refers to the number of cycles one thing's in per second, therefore does not multiply with core count. Simple physics, ninth/tenth grade material.

Hey no need to be a jerk..i am not an expert alright..

 

What i meant to say is for marketing purposes because people tend to think that the more it is the better..

The whole CPU only follows a single clock signal, which in this case cycles at 4GHz. Calling it 16GHz because it has 4 cores would be false advertising.

ok i get it...so the max speed is only 4Ghz in this case..thats why they advertised it as 4Ghz?

Yes.

 

Calling it 16GHz would be almost like selling a car with a top speed of 120mph as a 480mph car because it has 4 wheels.

I distinctly remember reading some newspaper ads 10+ years ago, when a retailer did exactly this: advertising a 2GHz 4-core CPU as "8 GHz". Totally annoyed the shit out of me with their false advertising, as having 4 cores doesn't mean you get one task done 4 times faster, it just means you can (theoretically) do different 4 tasks in the same time you do 1.

it depends on the task though
